RE: Upper Intake Question
An intake like that will KILL the low end torque on a stock motor. It would be good for a built or supercharged car that sees a lot of drag strip duty. It moves the horsepower and torque peaks waaaay up in the powerband.

RE: Upper Intake Question
Here is my review of my experience with this intake
Comp Cams Polymer Upper Intake[/b]
http://forums.stangnet.com/showthread.php?t=632123
I first purchased my Comp Polymer upper when I still had the stock 302. Mods at the time were; Cobra Lwr, 24lb Inj, 70mm TB, 73mm C&L, and 1.7RR. I had 3.27 gears, and stock virgin heads. Before installing the comp cam intake I had the virgin Cobra upper in place, so I can provide a comparison between these 2 setups.
The comp cam upper did sacrifice some bottom end, until about 3,500rpm. Above 3,500 the car was much more powerful. Never had it dyno'd just SOTP. The bad part was the low end loss, which was almost unbearable. Getting moving from a stop was embarrassing. I was actually unhappy with the comp cam upper, until I put in the 351w.
With my current setup, the comp upper is ideal, as it allows the Lightning Lwr to breathe at full capacity.
I would not recommend using this intake with boost however. I have had some trouble getting it to seal, and have found that silicone is a must between the upper and lower half of the Comp intake. I think boost would just blow this thing apart. When I move up to boost on this car I will be swapping the Comp upper for a TrickFlow, or other Al upper.
My recommendations for using this intake are...
Pair it with a Cobra/GT-40 lower, which should flow a little better than stock.
Swap gears for 3.55 or bigger to help diminish the low end power loss.
Any change made to the heads and cam to improve airflow will greatly enhance the upper end gains.
These intakes are great for h/c/i strokers, whether 302 or Windsor based. The added flow of the Comp upper will come in handy with the extra cubic inches. The loss of low end with a stroker motor will not be as noticeable.
Also, plan ahead.
Don't buy an intake that you will outgrow fairly soon
